host-to-multihost
termnetworking
One sender reaching many receivers at once: the one-to-many communication pattern.
Broadcast and multicast are its everyday forms, and the design question is always who is obliged to process the copy. Broadcast forces every station on the segment to look; multicast delivers only to those who subscribed, which is why streaming and routing protocols prefer it. The pattern's dark twin is the amplification attack, where a small one-to-many request is abused to flood a victim. Contrast with its mirror, multihost-to-host.
